Basic Openweathermap Trigger not working

Because the local NOAA weather for my area frequently goes down, I’ve switched to Openweathermap. I’ve got my API key and can readily add cards with current conditions and forecasts.

I’m trying to create a simple automation that turns on my air conditioning unit when the temp exceeds a certain value. Here is the config in HA:

The associated YAML:

platform: numeric_state
entity_id: sensor.openweathermap_temperature
above: "72"

The current temperature in my area right now, as reported by the Openweathermap card on my dashboard, is 77 F. But the automation isn’t triggering.

I must be missing something extraordinarily basic, but I cannot for the life of me figure it out. Any help would be appreciated.
